Optical structure: Adopt Paschen-Runge structure and Rowland circle device to reduce the influence of stress release caused by changes in ambient temperature and vacuum degree, and improve the accuracy and stability of the instrument.

Optical focal length: Grating radius 400mm, the longer focal length provides excellent resolution for the instrument.

Spectral range: detectable wavelength range (120 ~ 800) nm, can analyze elements including N, Li, Na, K and other conventional elements, to meet the needs of various matrix materials for test elements.

Entrance slit: slit width 12μm, fine entrance slit effectively filters out unnecessary stray light, avoids excessive saturation of light intensity received by the detector, and reduces the light intensity interference value between elements.

Light source lens: Quartz glass material MgF2 layer is used to ensure that the C, S, P, N and other ultraviolet wavelengths have the strongest light intensity, making the ultraviolet short-wave measurement results more reliable.
